Application filed Qctober 24, 1918. Serial No. 259,570.

To all whom it may concern:

Beit known'that I, ALBERT E. Jorrnson, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Preparing Insoles; and I do'hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it ap pertains to make and use the same.

This invention relates to machines for preparing soles, and more particularly to machines for preparing welt insoles of the type illustrated and described in Letters Patent of the United States to the present applicant, No. 1,212,490, dated January 16, 1917.

This type of sole is provided with marginal recesses in its flesh side to permit overlying portions of the counter and upper adjacent the recesses to be lasted therein and the ends of the'welt brought down to substantially the level of the heel seat. The inner edges of the overlying portions of the counter, upper and welt are positioned in a shoe substantially parallel to the portions of the edge of the sole adjacent the breast line and, therefore, in order for the recesses to properly receive such overlying portions, it is desirable that the inner edges of the recesses extend substantially parallel to said portions of the edge of the sole.

The machine illustrated and described in the application for Letters Patent of the United States, Serial No. 874,718, filed November 30, 1914, by the present applicant for preparing this type of sole, is provided with a pair of rotary gouging knives against which the sole is fed to form the recesses. As the gouging knives in said prior machine are maintained in a longitudinally fixed position in respect to their axes during the effective operation thereof, it will be seen that while this machine is adapted to form recesses of the character described in a sole having the sides of its shank, adjacent the breast line, parallel, it is not adapted to form such recesses in a sole having said shank edge portions oblique to each other.

Accordingly, one object of the present in vention is the production of a sole having marginal recesses in its shank portion for the reception of the adjacent overlying portions or the counter and welt, of such configuration as will bring the inner edges of the recesses substantially parallel to the portions of the edge of the sole adjacent the breast line, irrespective of whether or not said edge por tions of the sole are oblique to each other. To this end, a feature of the invention consists in the provision, in a machine of the type described in said co-pending application, of means for causing the gouging knives, during their effective operation, to follow the direction of the respective portions of the edge of the sole adjacent the breast line.

The machine illustrated and described in said co-pending application is not adapted to form recesses of difi'erentlengths, but as the portions of the counter and welt referred to vary in length from about five-eighths of an inch to one and one half inches, it is desirable that the length of the recesses conform to this condition.

Accordingly, another object of the invention is to provide for variations in the length of the recesses. To this end a feature of the invention includes the provision of means in a machine of the type referred to whereby marginal recesses may be formed of any desired length, so as to conform in length to the portions of the counter and welt to be set in said recesses in the respective shoes in which the soles are to be incorporated.

To the accomplishment of these objects and such others as may hereinafter appear, as will be readily understood by those skilled in the art, the invention comprises. the features and combinations of parts hereinafter described and particularly pointed out in the appended claims.

The preferred form of the invention is shown in the accompanying drawings, in which:

Figure 1 is a side view in elevation, partly broken away, of a machine embodying the invention; Fig. 2 is a plan view of the machine; Fig. 3 is a front view in elevation of the machine Fig. 4 is an enlarged sectional view taken on the line 41 of Fig. 1; Fig. 5 is a detail of one of the gouging knives; Fig. 6 is a sectionalview taken on the line 6-6 of Fig. 3; Fig. 7 is a sectional view taken on the line 7-7 of Fig. 2; Fig. 8 is a sectional view taken substantially on the line 8--8 of Fig. 2, looking from the left hand side of the machine; and Fig. 9 is a rear elevation partly in section of the parts shown in Fig. 8.

In the machine illustrated in the drawings, the sole is initially positioned upon a work supporting table 10 (Figs. 1 and 2), against a heel gage 12, and between oppositely disposed edge gages 14-14 mounted on the table. The edge gages 14 tend to centrally position the sole, and they comprise oppositely disposed fingers 16-16, the inner ends of which engage the edge of the sole and the outer ends of which are secured to the ends of the outer arms of levers 18-18 pivoted on the under side of the table. The levers 18-18 are connected to move in unison in opposite directions by intermeshing gear teeth formed on the ends of their inner arms and are swung in a direction to bring the inner ends of the fingers 16-16 toward each other by a spring 20 having one end connected to one of the levers 18 an-d its other end secured to the table. The inward movement of the fingers 16-16, when a sole is not positioned between them, is limited by the engagement of an adjustable stop screw 22 threaded through a lug on said table with a shoulder 24 on one of the levers 18.

The table 10 is moved toward and from the gouging knives 26-26 by a support 28 (Fig. 6) upon which the table is mounted and having its rear end pivoted on the frame of the machine. The support 28 is actuated by a toggle 30 having the outer end of one arm pivoted on the under side of the support 28 and the outer end of its other arm pivoted on the frame of the machine. By breaking the toggle 30, the support 28 and consequently the table 10 is lowered, and when the. toggle is straightened, as shown in Figs. 1 and 6, the sole is thereby brought into position to be acted upon by the gouging knives. The toggle 30 is actuated by a connecting rod 32 having one end pivotally connected to the knee of the toggle and its other end provided with an eccentric strap to engage arr-eccentric or cam 34 carried by the main shaft 36 of the machine. The shaft 36 is journaled in hearings in the frame of the machine and is driven by a pulley 38 loosely mountedthereon which is adapted to be connected to the shaft 36 through a one revolution clutch 40. (Figs. 2 and 6.) The clutch be of any suitable construction, such as the Horton type, and is thrown into operation by means of a foot treadle at the base of the machine which actuates the clutch to connect the shaft and pulley through a lever 42 pivoted on the frame of the machine.

The gouging knives 26 are carried by a shaft 44 journaledin the frame which is continuously driven through a pulley 46 (Figs. 1 and 2) secured thereto by a belt 48 which'connects the pulley with any suitable source of power. The gouging knives are adapted to be adjusted toward and from each other to position them laterally in respect to the sole, and simultaneously with such adjustment of the gouging knives, the heel gage 12 is adapted to be adjusted longitudinally .of the table 10 to position the sole longitudinally of the gouging knives. Such adjustments of the gouging knives and heel gage are effected in accordance with the size of the sole, by means of a size lever 58 (Figs. 1, 2 and 3) which is adapted to be moved across a scale 60 indicating sole sizes formed on a bracket 64 secured to the frame of the machine. The size lever 58 is pivoted on a shaft 66 journaled in the frame and is clutched to the shaft 66 when the machine is at rest, by a clutching device 68 (Fig. 8) hereinafter described. A pair of segments 70 (Figs. 2, 3 and 6) are secured to the shaft 66 and are provided with oppositely inclined cam grooves 72 which are engaged by studs or rolls 74-74 on gouging knife carriers 76-76 which are mounted to slide on a rod 78 having its ends secured to the frame of the machine. With this construction, it will be seen that by swinging the size lever 58 downwardly to locate it adjacent one of the smaller size numbers on the scale 60 that the carriers 76 will be moved toward each other and that by swinging the lever 58 in the opposite direction that the carriers will be moved away from each other. The carriers 76 comprise sliding blocks 80 mounted on the rod 78, upon the outer faces of which are secured the upper ends of plates 82, the lower ends of which plates are provided with apertures through which the outer hubs of the gouging knives project. On the in ner faces of the sliding blocks 80 are positioned the plates 84, the upper ends of which are bent outwardly and are provided with recesses which engage grooves in the heads of adjusting screws 86 threaded into the sliding blocks 80. The lower'ends of the plates 84 are bent outwardly to form depth gages 88 (Fig. 4) which engage the upper surface or flesh side of the sole when the latter is brought against the gouging knives, and which limit the depth of the cuts in the sole made by the gouging knives. The depth gages are cut away to permit the cutting edge of the gouging knives to extend therethrough, and to the outer ends of said depth gages are adjustably secured the edge guides 90 by means of screws 92 threaded into the edge guides and extending through slots in the depth gages. The depth gages are adjusted vertically by means of the adjusting screws 86 and are guided by screws 94 (Fig. 6) which extend through guide slots 96 in the plates 84 and are screwed into the sliding blocks 80. 7 4

The adjustment of the heel gage 12 is effected simultaneously with the adjustment of the gouging knives when the size lever 58 is moved, by a cam slot97 (Figs. 1 and 8) formed in a member of the hub of the size lever which is engaged by a stud or cam roll on the upper end of a lever 98 pivoted at 99 on a link 100, and the upper end of the lever 98 is guided by a stud thereon which engages a horizontal slot 102 in the frame of the machine. The lower end of the lever 98 is connected by a link 104 with an arm 106 projecting from a sleeve 108 (Fig. 2) pivotally mounted on a shaft 110 which is journaled in the frame of the machine. The sleeve 108 is also provided with an arm 11 which is connected by a link 114. with the heel gage 12. By repositioning the size lever 58 in respect to the size scale, the cam groove 97 will swing the lever 98 and through the connecting mechanism adjust the heel gage 12 in accordance with the position 'to which the size lever is moved and, therefore, in accordance with the size of the sole.

After th above described simultaneous adjustment of the gouging knives 26 and the heel gage 12 to accommodate the size of the sole to be acted upon and the sole is positioned upon the work supporting table 10, it is brought thereby into position to be acted upon by the gouging knives. When the shaft 36 is actuated, the table 10, which is auapted to slide on its support 28, and the heel gage 12 are moved forwardly in unison to cause the gouging knives to make recesses of the desired length in the sole. To permit such feeding movement of the table 10, its lower portion extends into a recess in the support and its lower surface is arranged in sliding engagement with a plate 116 (Figs. 4 and 6) supported by springs 118 in said recess. The table is held in the recess by gibs secured to the support which are adapted to be engaged by shoulders formed on the table and is guided by the side walls of the recess. The feeding movement of the table is accomplished through a link 120 (Figs. 1 and 6) having one end pivoted on the rear end of the table and its other end pivoted on the end of one arm of a bell-crank lever 122 which is secured to the shaft 110. Said bell-crank lever is actuated through a connecting rod 124 having one end connected to the arm 123 of the bell-crank lever, and the other end provided with an eccentric strap which is engaged by an eccentric or cam 126 carried by the main shaft 36 of the machine. The length of the feeding movement of the table 10 and consequently the length of the recesses formed by the gouging knives in the sole, may be varied by adjusting the connecting rod 124; lengthwise of the arm 123 of the bell-crank lever 122. To this end the connecting rod 12 1 is adjustably secured to th arm 123 by a bolt 128, upon which the connecting rod 124- is pivoted, which extends through an elongated slot 130 in the arm 123 and is secured in position in said slot by tightening a nut 132 threaded on the end thereof which clamps the arm between a shoulder formed on the stud and said nut. By loosening the nut 132 the connecting rod may be adjustedas desired relatively to the arm 123. The movement of the bell-crank lever 122 also moves the heel gage 12 in unison therewith, through the shaft 110 to which the bell-crank lever is secured, which actuates the heel gage through the link 100 connecting an arm 133 secured to the shaft 110 and the lever 98 which is connected as hereinbefore described to the heel gage through the link 104:, arms 106 and 112, and link 11 1.

At tie completion of the feeding of the sole past the gouging knives, the support 28 which carries the work supporting table 10 is swung downwardly which permits the sole to be removed. During such movement of the support 28, the table 10 and heel gage 12, through the described mechanisms, are returned to their initial positions. This cycle occurs at each omplete revolution of the main shaft 36.

The clutchin device 68 (Fig. 8) which connects the size lever 58 to the shaft 66 at the completion of each revolution of the main shaft and which disconnects the size lever and shaft 66 at the start of each revolution of the main shaft, comprises a lever 13 1 having one end pivoted at 136 on the hub of the size lever and having a shoe 138 formed thereon extending through an opening in the hub of the size lever. The lever is swung on its pivot to bring the shoe 38 into locking engagement with the shaft by means of a lever 1&0 pivoted at 1 12 the frame of the machine and having its snorter arm provided with a screw 143 havin its shorter arm provided with a screw 1 13 having a squared shank which extends through a slot 141 in the lever 68 which slot is concentric with the shaft 66 when the clutching device is in locking engagement with the shaft 66. The lever 140 is actuated by link 145 having one end provided with a slot through which extends a screw 146 threaded into the rear end of the lever 1410, and the other end of the link is pivoted on an arm secured to the rock shaft 110. At the completion of a cycle of operations of the machine, the lower end of the slot in the link engages the screw 1 16 which actuates the lever to clamp the shoe 138 down onto the shaft, while at the start of a cycle of operations, the slot in the link 145 relieves the pressure of the lever 1 10 on the shoe 138. A coiled spring 1 17 is disposed between the shoe 138 and lug on the size lever which maintains a certain amount of tension between the lever 13% of the clutching device 68 and the lever 1 10, but the tension of said spring is not sufficient to cause the shoe 138 to effectively clutch the shaft 66 when the pressure of the lever 140 is relieved as above described.

During the feeding of the sole, the shaft 66 is rotated in the direction of the arrow shown in Fig. 6 which through the cam grooves 72, stud 74 and gouging knife carriers 8O shift the gouging knives outwardly which cause the recesses to be formed oblique to each other. Such movement of the shaft 66 is effected through a sleeve 148 (Figs. 2, 6 and 7) mounted thereon and provided with gear teeth 149 which mesh with gear teeth on the end of the forward arm of a lever 150 pivoted on the shaft 110. The sleeve 148 is clutched to the shaft 66 at the start of this movement by the clutching device 152 which'consists of oppositely disposed dogs 154154 having their lower ends eccentrically pivoted on studs 156 secured to the sleeve. The upper ends of the dogs 154 tend to be forced apart by a coiled spring 158 between them. Upon the rotation of the Sleeve 148 by the lever 150 in one direction, one of the dogs 154 acts to lock the sleeve 148 to the shaft 66 and upon the rotation of the sleeve in the opposite direction, this dog is released and the other dog acts to lock the sleeve 148 to the shaft 66. When the sleeve 148 is brought back to its initial position the latter dog 154 engages a stop screw 160 threaded into a lug on the frame which swings the dog to disengage it from locking engagement with the shaft 66 so that at the completion of a cycle of operation both dogs are out of locking engagement with the shaft 66 as shown in Fig. 7. The lever 150 is actuated through a connecting rod 162 having one end adjustably secured to the rear arm of the lever 150 and its other end provided with an eccentric strap which engages an eccentric or cam 164 carried by the main shaft 36.

Because of the variation in the relative obliqueness of the shank edges of different soles adjacent the breast line and because of the variations in the length of the recesses in different soles it is necessary, in order that the recesses be formed with their inner edges parallel to such portions of the edges of the different soles that the degree of movement of the gouging knives away from each other during the feeding of the different soles be varied accordingly. This is effected by adjusting the connecting rod 162 along the rear arm ofthe lever 150 which thereby varies the amount of movement of the shaft 66 through said lever 150. Such adjustment of the connecting rod 162 is effected by loosening a nut 166 threaded on the end of a screw 168 which extends through an elongated slot 170 in the rear arm of the lever 150. The screw 168 serves as a pivot for the end of the connecting rod and is clamped in position in the slot 170 by tightening the nut 166 which cooperates with a shoulder formed on the screw 168 to grip the lever 150 between them.

During the feeding movement the springs 118 which tend to press the work supporting table 10 toward the, gouging knives yield sufficiently to permit the sole to adjust itself to the side edge guides'90.

In operating upon a welt insole the location of the sole beneath the gouging knives 26 is such that-the gouges extend at each side from the edge of the sole to the between-substance, that is, the lineof cut is so controlled that'the path of travel of the inner edge of the knives 26 is coincident with the outer edge of the between-substance at each side of the shank of'the sole. The gouging knives 26 are provided with the usual cutting edges 172 (Figs. 4 and 5) and in order to form :the recesses-withclean out inner edges to produce a clearly defined sewing shoulder at the outer edge of the between-substance, the gouging knives in the illustrated machine are additionally provided with=circularcutting edges 174 formed on disks which are positioned adjacent the inner sides of'the members provided with cutting edges 172, by a collar or hub 176. As shown in Fig. '5 the diameter of the disk cutters 174 is equal to the diameter of the gouging cutters 26, thus providing for the same depth of cut'by each and preventing a weakening of the feather by an incision at the base of the sewing shoulder. Located on the outer faces of the gouging knives are the collars or hubs 178, and the several members of the gouging knives are secured together between plates 82 and 84 of the knife carriers 80 which plates engage shoulders formed on the collars or hubs 176 and 178.

The sole as it is fed is held down on the work table adjacent the gouging knives by the depth gages 88 and in the illustrated machine it is held down in advance of the gouging'knives by feet 180 (Figs. 1 and 3) formed on the ends of downwardly spring pressed plungers 182 mounted in brackets secured to the front of the gouging knife carriers 80.

In order to form recesses having their inner edgesparallel, the shaft 66 which carries the grooved segments is adapted to be operatively disconnected from the driving shaft 36, so that Whenthe machine is operated the segments remain stationary and therefore, do not act to shift the gouging knives. This may be accomplished by disconnecting the connecting rod 162 from the levgr 150'through which the shaft 66 is actuate The'gouging'knives may be adjusted'independently of the heel gage 12, by means of a hand wheel 184 secured to one end of the shaft 66, in the same manner as illustrated and described in said co-pending application.
